DESCRIPTION
The ADG3232 is a mux level translating device designed on a
submicron process that operates from supplies as low as 1.65 V.
The device is guaranteed for operation over the supply range
1.65 V to 3.6 V. It operates from two supply voltages, allowing
bidirectional level translation, i.e., it translates lower voltages to
higher voltages and vice versa. The signal path is unidirectional,
meaning data may only flow from A to Y.
A1 and EN Input
The A1 and enable (EN) inputs have V
the part can accept logic levels of V
value of the supply being used. Both these inputs (A1 and EN)
are capable of accepting inputs outside the V
There are no internal diodes to the supply rails on these pins, so
they can handle inputs above the supply but inside the absolute
maximum ratings.
Operation
Figure 3 shows the ADG3232 in a typical application; the signal
paths are from A1 or A2 toY. The device will level translate the signal
applied to A1/A2 from a V
be either to a higher or a lower supply) and route the signal to the
Y output, which will have standard V
The supplies in Figure 3 may be any combination of supplies, e.g.,
